/* Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
useless:
- It returns the empty string when LANG is set to a locale of the
form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
LC_CTYPE file.
- The environment variables LANG, LC_CTYPE, LC_ALL are not set by
the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
- The documentation says:
"... all code that calls BSD system routines should ensure
that the const *char parameters of these routines are in UTF-8
encoding. All BSD system functions expect their string
parameters to be in UTF-8 encoding and nothing else."
It also says
"An additional caveat is that string parameters for files,
paths, and other file-system entities must be in canonical
UTF-8. In a canonical UTF-8 Unicode string, all decomposable
characters are decomposed ..."
but this is not true: You can pass non-decomposed UTF-8 strings
to file system functions, and it is the OS which will convert
them to decomposed UTF-8 before accessing the file system.
- The Apple Terminal application displays UTF-8 by default.
- However, other applications are free to use different encodings:
- xterm uses ISO-8859-1 by default.
- TextEdit uses MacRoman by default.
We prefer UTF-8 over decomposed UTF-8-MAC because one should
minimize the use of decomposed Unicode. Unfortunately, through the
Darwin file system, decomposed UTF-8 strings are leaked into user
space nevertheless.
Then there are also the locales with encodings other than US-ASCII
and UTF-8. These locales can be occasionally useful to users (e.g.
when grepping through ISO-8859-1 encoded text files), when all their
file names are in US-ASCII.
